Depends what you are into:
Driving: Assetto corsa, iRacing, basically most racing simulators
Flying: VTOL VR, DCS, MS Flight Sim 2020, Ultrawings
Shooting: Onward, Pavlov, Contractors, Hot dogs horseshoes and handgrenades
Social: VRChat, Rec Room
Story/single player games: Half Life Alyx, Boneworks, Skyrim or Fallout 4
Stealth: Budget Cuts
Others: Beat saber is a must
I'd say VR is finally at the point where there are great games in most genres, and we are finally past the point where a stupid, 2 hour "experience" costs $40, in other words, most games being released for it now are not gimmicks. Honestly my recommendations are a little out of date. I've pointed out what I would consider "the classics" at this point
